The bill Schleswig was a former coal mine at the Gemarkungs limit of Dortmund neighborhoods isopods and Brackel . From 1910 to 1912, Eisenstein was also mined to a small extent .
Mining history
At the Schleswig colliery, which was operated by the Hörder Bergwerks- und Hütten-Verein , two shafts were sunk from 1855 , one for extraction and one for drainage . The Hörder Verein rented Schleswig on September 5, 1852 and a little later drilled a 36- inch thick seam . The colliery was awarded on February 15, 1855 , in 1859 it began mining, and at the same time the narrow-gauge horse-drawn railway between the Schleswig colliery and the Hermannshütte was put into operation. The promotion of mine went almost entirely to the in Hörde founded Hermannshütte .
On November 15, 1859, the coal regions merged to form the joint mine, the Zeche Vereinigte Hörder Kohlenwerk . The seams, Dicke Kirschbaum (Mausegatt) , (in the hanging wall especially Eisenerz- Blackband ), Eiserner Heinrich and Hühnerhecke (Finefrau) were mined . The mountains were interspersed with numerous saddles and hollows and were very disturbed. The edible coal was considered noble and bold. As early as 1862, a separate locomotive had to be added to the horse-drawn tram, as production increased. In 1865, 139,000 tons of annual production had already been achieved. In 1872 a coking plant was built, it was put into operation in 1873, but was put back in the cold in 1874 because the company's own coal did not provide usable coke . Between 1880 and 1886 this coking plant was put back into operation.
From 1874, the Hörder coal works built another shaft in the immediate vicinity, the Holstein mine . Both systems were connected to the railway line in 1877, initially as a narrow-gauge railway, then in the course of the year on standard gauge . At the deepest sole (Schleswig 540 m, 510 m Holstein) both pits were through a 1.8 km long straightening path connected; the gradient ensured that the pit water was drained away . Above ground, the two shafts were linked by a connecting railway from 1885.
A specialty of Schleswig was the bathhouse and brine bath operated by the colliery . In the small bathing facility, the salty pit water was used for therapeutic applications. The bath house is still preserved and is used as a residential building.
In May 1889 there was a serious incident after a week-long strike that affected almost all the mines in the Ruhr area . Because of the unrest, the military was ordered to mine. An officer told the crowd to disperse. When this did not happen, there was sharp shooting. Seven people were hit, four of whom were killed. Among those killed was a mother with her child.
The Schleswig shaft was finally closed and filled on July 15, 1925 . Three years earlier, the mining officials' settlement Am Knie , which has survived to this day, was completed and occupied near the colliery . The civil servants' settlement Am Knie was built in 1922 by Phönix AG for mining and smelting operations , to which the Hörder Verein was now part, based on designs by the Essen architect Fritz Schupp . For the miners ' children , a school was also set up in the Neuasseln colony miners' settlement, today's Fichtegrundschule.

Cable cars departing from the Schleswig dump
From 1904 until the 1930s, tailings were transported from the Schleswig heap to Kurl and Scharnhorst by cable car, which was used in the mines there to fill the shafts.
The cable car leading to Kurl was the first line to go into operation in December 1904. It had a length of 4610 m and was laid out in a gentle arc with a radius of around 20 km to avoid expensive angular stations. The cable car, which went into operation at the beginning of 1907 and connected the mining dump Schleswig with the Scharnhorst colliery, was 3970 m long.
Both cable cars were set up for uninterrupted operation. They had two suspension ropes that were parallel to each other at a distance of 2.3 m and ran over supporting pillars at certain intervals. One rope was intended for the outward journey of the loaded wagon, the other for the return journey of the empty wagon. The pull rope was in constant motion and was guided around sheaves in the stations. It was driven by a drive pulley with a diameter of 2.5 m, which was set in rotation by means of a gear transmission and belt drive by a 100 HP motor specially developed for cable car operation. In the landscape there is no longer anything to suggest the cable cars.
Gas explosion when removing the Schleswig dump in 1924
Fortunately, the Schleswig colliery was spared serious mass accidents. The most momentous accident occurred on September 16, 1924 - albeit over days when the mine dump was being cleared. According to the mine safety office in the Prussian Ministry of Commerce and Industry, this accident was "unique in terms of scope and consequences".
During clearing work on the southern heap ridge, around 300 cubic meters of heap mass slipped into the gorge between the southern and northern heap ridge with a dull roar. The slide released large masses of gas that had accumulated in the fissures and cavities of the burning heap as a result of smoldering and ignited on small, glowing coal particles under the sudden influx of oxygen. The effect of the explosion was intensified by the relaxation of high-pressure water vapor.
Of the 40 workers working on the dump, 29 were able to get to safety unharmed and eleven were killed. Eight of them had initially been able to escape into a tunnel that crossed the northern ridge of the dump. Trams loaded with waste material were brought through this tunnel to the loading station of the two cable cars.
But then there was a second explosion in the narrow tunnel, which was so violent that the loaded trucks and all eight workers were thrown out of the tunnel, which were rammed into place with a chock. Her uninjured work colleagues found her with smoldering work clothes, broken bones and skull injuries, but still alive. Despite quick help from the village doctors who had rushed over, none of them had a real chance of survival.
